Riley was found April of last year with a gunshot wound to his chest inside a rented room at the Cavern City Inn on Yellowstone Road.

"Witnesses in the hotel stated they could hear the two of them yelling at each other and what some described as multiple physical domestic violence altercations continuing to occur inside the motel room which finally led up to the shooting," Sgt. Jeff Hernandez said in a news release.

Hernandez said in the news release that there were several witnesses interviewed at the time of the incident. Detectives told the Current-Argus following the shooting in April that foul play was suspected in Riley's death.
